I noticed in the field, after spraying cytokinin as a form of support for the ears of corn plants at the age of 7 leaves and 9 leaves to maximize productivity, that the stalk length was inhibited at 2.30 meters, and it was 20% carrying two ears of corn. The length of the ear, the number of grains and rows, and the size of the stalks were very good. Taking into account the fertilization was very good and the control of armyworm was achieved at a rate of 85 to 90%.
